| Abstract |
We have carried out a basic experiment in order to develope a super high-resolution optical microscope which transcend the limitation of diffraction and the wavelength of lightwave. The image of this scope is composed by measuring the evanescent wave which is localized on the surface of the testing materials. A detecting probe was fabricated with a single mode optical fiber to be sharpened by the chemical etching, and drived by PZT. The standing wave of 0.33μ textrm m wavelength evanescent wave which was generated from the 0.78μ textrm m-wavelength semiconductor laser was detected by the 0.5μ textrm m-thickness optical fiber probe. |
